Davey Pressure Tank 40L: Why This Tank Protects Your Pump and Improves Water Pressure

If your water pump is constantly turning on and off, losing pressure, or wearing out faster than expected, the problem often isn’t the pump it’s the lack of a proper pressure tank. The Davey Pressure Tank 40L is designed to stabilise water pressure, reduce pump cycling, and extend the life of your entire water system.

Whether you’re running a household pressure system, rainwater tank setup, or rural water supply, adding a 40L pressure tank is one of the smartest upgrades you can make.

What Does a Pressure Tank Actually Do?

A pressure tank stores pressurised water so your pump doesn’t need to start every time you open a tap. Instead of the pump reacting instantly, the tank supplies water first, reducing stress on the motor.

• Prevents rapid pump cycling
• Maintains consistent water pressure
• Reduces electrical consumption
• Extends pump lifespan

Without a pressure tank, pumps work harder than they should leading to premature failure and higher running costs.

Why Choose the Davey Pressure Tank 40L?

The Davey Pressure Tank 40L is built specifically for Australian conditions and designed to integrate seamlessly with Davey pressure pumps and controllers.

Key Advantages

• 40L capacity ideal for residential and light commercial systems
• Internal bladder design for consistent pressure delivery
• Reduces pump starts and stops dramatically
• Compatible with most Davey water pump systems
• Durable construction for long-term reliability

This tank hits the sweet spot large enough to improve system performance without taking up excessive space.

Is a 40L Pressure Tank the Right Size?

Choosing the correct tank size is critical. A 40L pressure tank is ideal when:

• You want smoother pressure at taps and showers
• Your pump services multiple outlets
• You experience frequent pump cycling
• You want to reduce pump wear without oversizing

For most Australian homes using a standard water pump, 40L offers a strong balance between performance, cost, and footprint.

Perfect Pairing With Davey Pumps

This pressure tank is commonly paired with Davey pump systems for rainwater harvesting, household pressure boosting, and rural tank-to-house setups.

When installed correctly, the tank allows the pump to run in longer, more efficient cycles — exactly how pumps are designed to operate.

Installation & Maintenance Considerations

Installation is straightforward for licensed plumbers and pump technicians. The tank should be:

• Installed close to the pump outlet
• Correctly pre-charged to match system pressure
• Mounted on a stable, level surface

Minimal maintenance is required, but periodic pressure checks ensure peak performance.
